3 children have a total of $3610.
Charlie has $110 more than Adam.
Adam has 3 times as much as Bryan.
- How much does Charlie have?
- How much does Adam have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Adam has = 3 u
Amount that Charlie has = 3 u + 110
Total amount that Charlie, Adam and Bryan
= 1 u + 3 u + 3 u + 110
= 7 u + 110
7 u + 110 = 3610
7 u = 3610 - 110 = 3500
7 u = 3500
1 u = 3500 ÷ 7 = 500
Amount that Charlie has
= 3 u + 110
= 3 x 500 + 110
= 1500 + 110
= $1610
(b)
Amount that Adam has
= 3 u
= $1500
(c)
Amount that Bryan has
= 1 u
= $500
Answer(s): (a) $1610; (b) $1500; (c) $500
